STOVE WITH CIRCULAR SHAKING GRATE.

Specification of Letters Patent No. 7,598, dated August 27, 1850.

To all whom t may concern Be it known that I, EDWARD B. FiNoi-r, ofPeekskill, in the county of Westchester and State of New York, haveinvented a new and useful Improvement in a Stove with a CircularRotating or Shaking Grate; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which-Figure l, is a perspective view. Fig. 2, is a vertical section throughthe center. Fig. 3, is a plan of the seat of the fire-box. Fig. 4, is aplan of the top plate of the ash box. Fig. 5 is a detached view of thesliding segment.

Similar letters of reference relate to corresponding parts in all thefigures.

The nature of my invention consists in having the bar which supports thecircular rotary or shaking grate, cast with and forming part of the topplate of the ash box and in providing a sliding segment for the purposeof closing the slot or aperture in the seat through which the lever forshaking the grate works.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and use.

A, is the floor plate.

B, B, are the sides of the ash-box.

C, is the top plate having a bar D, cast with and forming partI of it.d, is a pin or fixed center on the bar D. E, is the circular gratehaving a hole or socket at its center fitting easily on the pin d, onwhich it' is capable of being made to rotate. F, isa lever attached tothe circular grate E. G, is the seat of the fire box having an innerflange g, which keeps the circular grate E, down in its place. H, I-I,are ears cast on the seat G. The seat Gr, rests on the top plate C, andis secured to it by bolts I, I, which pass through holes z', z', in theears H, H, and top plate C, and through the Hoor plate A, and aresecured by nuts y', j, under the floor' plate. A slot is cut in the seatG, through which the lever F works. n is a sliding segment or part of aring of metal, ,sliding in a recess below the seat G, and moving withthe lever F, for the purpose of closing the said slot in the seat Gr,and shutting` the draft. The sliding segment h, rests on the plate C,and is provided with a notch fitting over the lever F; it is kept in itsplace on the lever by shoulders z' on the sides of the lever. J, is atrap in the grate E, which works on centers 7c, and is kept up by asliding pin Z, under the lever.

It is usual in stoves constructed on this principle with rotary orshaking grates to have the seat G, of the fire box cast with the topplate C, of the ash box, and the bar D, is usually riveted or bolted tothe said top plate and is very liable to become loosey by the `action ofthe fire or by the shaking of the grate, but this objection will beobviated by having the bar (D) cast to the top plate (C). The seat (G)and the top plate (C) are cast separately in my stove as it would beimpossible to introduce the grate between the bar (D) and the flange (g)on the seat (Gr) if the top plate of the ash box and the seat of thefire box were cast together in the usual manner, neither could thesliding segment (71,) be inserted.

wWhat I claim as new and desire to secure by Letters Patent is- Castingthe seat (Gr) of the fire box separate from the top plate (C) of the ashbox, having the bar (D) carrying the center or pin (d) for supportingthe grate, cast with, and forming part of the top plate (C) of the ashbox substantially as described and for the purposes set forth.
